make.variance {CollocInfer}

Variance Functions

Description

Returns a list of functions that calculate a (possibly state and parameter dependent) variance.

Usage

make.cvar()

make.var.SEIR()

Details

make.cvar requires the specification of further elements in the list. In particular the element more should be a list containing

Value

A list of functions that calculate a variance function and its derivatives, in a form compatible with the collocation inference functions.

make.cvar

returns a variance that is constant but may depend on parameters

make.var.SEIR

returns a state-dependent transition covariance matrix calculated for the SEIR equations.
